Ok i put my cam in and was recommeneded the following grind Intake: opens @ 26 degrees BTDC (before top dead center) closes @ 66 " ABDC (after bottom dead center) add 180 " total 272 degrees duration Exhaust: opens @ 66 degrees BBDC (before bottom dead center) closes @ 26 " ATDC (after top dead center) add 180 " total 272 degrees duration so i guess that makes it 272/272 with 318 lift...does that sound about rigth? What do you guys think?

Hey Guys Just a quick question, i am getting my cam from a N42 reground for my :P90 and i was wondering if anyone had any expierence with a reground cam in a similar set up, ie, im after the duration, timing details. What i want and what i have *the cam must be daily drivable (not overly agressive) *has to idle and start easily *Triple 45mm Webbers *Ported and Polished P90 *L28 with Flatops Any suggestions or details from people with a similar setup would be welcome

4 cyl? Whos talking about 4 cyl? RBs are a 6.......

So getting more power out of the RB20 is a simple as configuring the ECU? The only reason i wanted to go an RB25 is because its just a more powerful motor out of the box. And because i know someone who is getting an RB20 in there Z and i need to stay on top

Yeah i can see what your saying, and your info on the RB20, while suprising, is worth thinking on. Im not all for the new engine in old Zed thing (doesnt mean i dont like them, just means its not all i ever think about), my aim is to have a strong, reliable, economical (off boost) engine for daily driving. Will the 3ltr Turbo give me this? Also, as i am in australia we dont have easy access to L28 Turbo parts as the 280z(x) Turbo was not offered to us, so access to these parts are tricky at best. In australia a half cut Rb25 will set me back under 2k USD (around 3 here), so they are not that expensive for what they offer. Thanks

Well i was gonna do that, but after talking with some people i was told that the gain would be 20-40 HP max. I am getting 167 N/A (Triple Carbs) at the moment, so spending 2-3K on a turbo, hardly seems worth the money. But if it can be done decently with 1-1.5k, well thats a big difference But im open to opinions

Hey Guys, At the risk of being tared and feathered i just wanted to see what sort of experiences you guys have had with the above engines in to a Z. Now i know that the 25 can be tuned way past the 20 (obviously) but in a standard guise, with perhaps an aftermarket intercooler etc, how will the two react to slight modifications. As i understand it a business in Brisbane has alot of experience with these conversions, the price difference is about 1k (5k for RB20 conversion and 6k for the 25). As im not going to be chasing a 10sec quarter, i want something that is daily driveable, whilst maintaining some urge. Is the price difference worth it if im not chasing big HP numbers? Are there any advantages one has over the other (aside age and Cubes) Thanks Guys

wow, Thanks heaps for that, the article will come in very handy, i bet there were loads of people gunning for that car, youve dont very well. Just a couple of questions about the car itself, how does she drive as a daily driver. Is it tight enough to drive around off boost? Im sort worried about planting my foot coming out of a corner and just crossing the thing up, i am worried about too much power. AS it stand my L28 makes (a very spirited) 110kw at the wheels, so the 1JZ standard is gonna make almost double that. SO yeah basically i just would like to know how easy the old girl is to live with. Thanks heaps for the info

Hey guys, I have a friend of mine who is offering me a excellent stock 1jz (Twin Turbo) and im wondering if anyone knows anything about this conversion. Im aware that the main things are mounts, exhaust manifolds, breaks and drive trains. But i was wondering if there are any knowledgeble people out there with this sort of knowledge. As far as manual gearboxes go, i was informed that a W58 from a N/A supra would be my only option. But would it need to be strengthend. I assume i would need CVs from a 280 to strengthen the back end. A rough price would also be great or if anyone knows someone who has also attempted the job... Thanks guys
